The Emmons Glacier is on the northeast side of Mt. Rainier. It is the largest glacier in the contiguous United States at 4.3 square miles ( 11 square kilometers ). The Fryingpan Glacier is much smaller and sits on the eastern side of Little Tahoma Peak. After the upper portions of Sunrise and Mt. Rainier itself were enveloped in clouds parts of the Emmons and Fryingpan Glaciers were still visible from the road to Sunrise.
